In my home I have sun-shade that I can control via a handheld transmitter. I already figured out that it is sending on 868 mhz.

Now I'd like my raspberry to read send those signal instead (or as well as) the handheld remote.

The main problem I am currently facing is that I find quite a lot of tutorials on how to do that with 433 mhz modules and a ton of hardware modules.

For 868 mhz I just can't find a tutorial nor the hardware that I need. My 433 modules were super cheap thingies... Aren't there the same ones for 868 mhz.

I live in Austria (Europe) so something available in Europe would be nice :) Any hints are very very welcome!!!!

What you need to look at is the IEEE_802.15.4 standard specification. That include many popular protocols for the frequency you are interested in, such as: ZigBee, ISA100.11a, WirelessHART, MiWi, SNAP, and Thread.

That frequency belong to the Unlicensed ISM/SRD bands: 863.0 – 870.0 MHz (ETSI EN 300 220). So there are tons of devices Arduino, RPi etc devices that you can use to transmit.

Also check LoRa devices.
